Manufacturer profile
Hybrid Electronics sources Walsin Technology Corporation passive components across one of the world's largest MLCC and passive-component portfolios — multilayer ceramic capacitors (0201 / 0402 / 0603 / 0805 / 1206 / 1210 / 1808 / 1812 / 2220 / 2225 in NP0 / C0G / X5R / X6S / X7R / X8R dielectrics, general-purpose, high-cap low-ESL 0508 / 0612 reverse-geometry, high-voltage 200 V – 4 kV, and MT / RT AEC-Q200 automotive), chip resistors (WR04 / WR06 / WR08 / WR12 general-purpose thick-film, TF-series thin-film precision, WSC / WSK low-ohm current-sense, WRA / WA arrays, WK anti-surge, MR automotive AEC-Q200), chip inductors (WLC / WLN multilayer, WPN shielded wire-wound power inductors, WMF SMD EMI ferrite beads), chip antennas (WCA Wi-Fi / Bluetooth / GPS), varistors (WMV metal-oxide, TVS-C protection), ferrite cores (F / K / K5 for power inductors), piezo & ceramic resonators from the Wintron line (WPP series), and RF / microwave high-Q capacitors from the Passive Plus line (PPI PP high-Q). Same-day quotes, traceable stock, and OEM-excess sourcing since 1995.
Walsin Technology Corporation was founded in 1992 in Taipei, Taiwan as a passive-component spin-out from the Walsin Lihwa Group (one of Taiwan's largest wire, cable, and stainless-steel conglomerates). Walsin Technology today is one of the world's largest producers of multilayer ceramic capacitors (MLCC) and a top-tier supplier of chip resistors, chip inductors, ferrite beads, chip antennas, varistors, ferrite cores, piezo / crystal resonators, and RF / microwave high-Q capacitors. Walsin competes directly with Yageo, Murata, TDK, and Samsung Electro-Mechanics in the global MLCC market, and its catalog covers case sizes from 01005 through 2225 in NP0 / C0G / X5R / X6S / X7R / X8R dielectrics, general-purpose / high-cap-low-ESL reverse-geometry (0508 / 0612), high-voltage (200 V – 4 kV), and MT / RT automotive AEC-Q200 grades. Walsin's chip resistors, WLC / WLN chip inductors, WPN shielded power inductors, WMF ferrite beads, WCA chip antennas, WMV varistors, and Wintron-heritage WPP piezo resonators ship into virtually every high-volume application category — smartphones, PCs and servers, automotive infotainment / ADAS / xEV, industrial, medical, and telecom / 5G infrastructure.
Walsin Technology has built its portfolio through both organic growth and a series of targeted acquisitions and joint ventures: Prosperity Dielectrics Co. (PDC) — MLCC dielectric-materials specialist owned since the 1990s and the backbone of Walsin's in-house dielectric development; Ever Ohms Technology — chip-resistor specialist folded into Walsin's WR-series resistor line; Sfi Electronics — earlier passive-component and resonator business absorbed into the Walsin catalog; Wintron Technology (2009) — the Taiwan piezo, ceramic-resonator, crystal, and MLCC maker that gave Walsin the WPP-series ceramic resonator and additional MLCC capacity; and Passive Plus, Inc. (PPI) — the U.S.-based high-Q / high-power RF and microwave capacitor specialist whose PPI PP high-Q, high-voltage, and broadband RF caps now round out Walsin's high-frequency portfolio. Hybrid Electronics has sourced Walsin passive components since the mid-1990s — long before the Wintron and Passive Plus rollups. Engineers still hunt for parts by the original legacy names: pre-2010 Walsin MLCC production before the X7R specification tightening, older WR04 first-revision chip resistors, discontinued first-gen WLC wire-wound inductors, older WMF 0805 ferrite beads, pre-Wintron piezo lot codes, discontinued 2225 HV MLCC revisions, and pre-2005 Sfi merger-era parts. We source obsolete, hard-to-find, and allocated Walsin parts from OEM excess, CEM surplus, and traceable secondary channels when authorized distributors show zero stock or long lead times.
Our line card spans the full Walsin Technology portfolio — from current-production 0402 / 0603 / 0805 / 1206 MLCC across NP0 / C0G / X5R / X7R / X8R dielectrics, WR04 / WR06 / WR08 / WR12 thick-film chip resistors, WSC / WSK low-ohm current-sense resistors, WLC multilayer chip inductors, WPN shielded power inductors, WMF SMD ferrite beads, WCA chip antennas, and WMV metal-oxide varistors shipping into automotive, industrial, medical, and 5G / telecom programs, to legacy pre-2010 MLCC production, older WMF ferrite-bead revisions, first-gen WLC inductors, pre-Wintron WPP piezo lot codes, and pre-2005 Sfi-merger passive parts still qualified into legacy industrial, mil-aero, and legacy telecom systems.

Walsin Technology's catalog spans more than three decades of passive-component development — from the 1992 Taipei founding and 1990s Prosperity Dielectrics (PDC) integration, through the Sfi Electronics and Ever Ohms acquisitions, the 2009 Wintron Technology deal, and the Passive Plus (PPI) rollup. Along the way, several legacy revisions, dielectric formulations, and lot codes were rationalized that defense, industrial, medical, and legacy telecom BOMs still specify. Hybrid Electronics sources these end-of-life and legacy families from OEM excess, contract-manufacturer surplus, and traceable secondary channels:
Send an RFQ with quantity, target date-code range, and any traceability requirements (COO, MSL, factory sealed, DPAS-rated) — we return same-day availability from stock or an ETA from our sourcing network.
General-purpose 0402 / 0603 / 0805 / 1206 X7R / X5R / C0G MLCC, MT-series AEC-Q200 automotive MLCC, high-voltage 1808 / 1812 / 2220 / 2225 HV MLCC, WR04 / WR06 / WR08 / WR12 thick-film chip resistors, WSC / WSK low-ohm current-sense resistors, WLN / WLC multilayer chip inductors, WPN shielded power inductors, WMF SMD ferrite beads, WCA chip antennas, and WMV metal-oxide varistors are our highest-volume Walsin quote categories. Pre-2010 MLCC, older WR04 first revisions, first-gen WLC wire-wound inductors, older WMF 0805 ferrite beads, pre-Wintron WPP piezo lot codes, discontinued 2225 HV MLCC revisions, and Passive Plus (PPI) PP RF / microwave high-Q caps are steady low-volume sourcing lines for defense, industrial, medical, and legacy telecom customers.
Yes. Walsin Technology Corporation is consistently ranked in the global top five MLCC producers alongside Murata, Samsung Electro-Mechanics, TDK, and Yageo, shipping billions of pieces monthly across the 01005 / 0201 / 0402 / 0603 / 0805 / 1206 / 1210 / 1808 / 1812 / 2220 / 2225 case sizes in NP0 / C0G / X5R / X6S / X7R / X8G / X8R dielectrics, from general-purpose to reverse-geometry low-ESL, middle-to-high-voltage (200 V – 4 kV), and MT / RT automotive AEC-Q200 grades. Walsin is also a top-tier chip-resistor, chip-inductor, ferrite-bead, chip-antenna, and varistor supplier — a full-line passive-component competitor to Yageo.
Walsin was spun out of the Walsin Lihwa Group in 1992 and grew its passive-component footprint through a series of targeted deals: Prosperity Dielectrics Co. (PDC) — MLCC dielectric-materials specialist owned since the 1990s, the backbone of Walsin's in-house dielectric development; Ever Ohms Technology — chip-resistor specialist absorbed into Walsin's WR-series line; Sfi Electronics — earlier passive-component and resonator business folded into the Walsin catalog; Wintron Technology (2009) — the Taiwan piezo, ceramic-resonator, crystal, and MLCC maker that added WPP-series resonators and further MLCC capacity; and Passive Plus, Inc. (PPI) — the U.S.-based high-Q / high-power RF and microwave capacitor specialist whose PPI PP high-Q, high-voltage, and broadband RF caps round out Walsin's high-frequency portfolio.
Yes. Both product lines are part of Walsin Technology today and continue to ship under their original Passive Plus (PPI) and Wintron brand marking and part-number families. We quote PPI PP-series high-Q, high-voltage, and broadband RF / microwave capacitors (0201 – 4040 NP0, 50 V – 7.2 kV) and Wintron WPP-series ceramic resonators (2 MHz – 60 MHz) — both original-brand factory-marked stock and current Walsin-era packaging. Send us the exact PPI or Wintron part number and quantity and we'll cross-reference to the current Walsin equivalent.
Yes. Original Wintron-marked ceramic resonators and piezo devices (pre-2009 Walsin acquisition), original Sfi Electronics-marked passive parts (pre-2005 merger), original Ever Ohms-marked chip resistors from before the WR-series absorption, and original Passive Plus (PPI) PP-series high-Q RF caps from before the Walsin-era process refresh are all steady sourcing lines for legacy industrial, medical, mil-aero, instrumentation, and legacy telecom BOMs. Send us the exact legacy part number and quantity and we'll cross-reference to the current Walsin Technology equivalent.
